Various types of rock such as diabase , basalt and dolomite as well as other mineral additives are used as the basic material for the production of rock wool . These rocks can be extracted in open-cast mining. Production begins with the melting of the rock at a temperature of around 1500 ° C. The molten rock is then broken up into fibers. Binding and impregnating agents are already added to the fibers . The fibers treated in this way are collected in a collecting chamber to form a wool fleece. This fleece is compressed to the desired consistency and then cured at temperatures of around 230 ° C. The compression, the binder content and the orientation of the fibers in the wool are decisive for the specific requirements that the finished product will meet.
HECK Wall Systems GmbH & Co.KG (previously: BASF Wall Systems GmbH & Co.KG) in Marktredwitz has been part of the ROCKWOOL Group since January 1, 2014.
